B | 针对大量用户收到7.7 级预警信息一事，成都高新减灾研究所发布情况说明。通报显示：8月24日8:26四川宜宾长宁发生4.7级地震，成都高新减灾研究所的大陆地震预警网对该地震的预警震级序列依次为7.7级（震后第5秒）、6.4级（震后第6秒）、3.7级（震后第7秒）、4.1级（震后第8秒）、3.9级（震后第16秒）。    University institutions all over the world are interested in ambitious applicants and always help students adapt to a new place. They are welcomed. Young academics who have chosen education in Russia have shared their experience of studying abroad. They talked about their achievements and how their life and work at South Ural State University (SUSU) is arranged.,Dr. Bagaleu Uday from Warangal, India Came to Russia in 2018,© Bagaleu Uday/Personal archiveBagaleu Uday Bagaleu Uday © Bagaleu Uday/Personal archive,I have been living in Chelyabinsk for three and a half years now. After defending my thesis in chemical engineering at the National Institute of Technology Warangal, India, I decided to continue my research in another country. And when I heard about the latest Russian developments in the field of biotechnology, I had a burning desire to work at SUSU.,For a scientist, moving to another country is a great opportunity to raise his scientific work to a higher level. I learned a lot in the field of food and biotechnology and can now compete with strong researchers. Moreover, because of the education and experience I gained in India, I have been offered an interesting job in the field of packaging material development.,Now I am a senior researcher at the SUSU Department of Food and Biotechnology. This year alone, I have had four publications in Scopus magazine (Scopus is a unified international scientific database - ed. note Sputnik). It was also a great achievement for me to win the young scientist competition. I won a three-year grant to develop a double food-enriching emulsion.,To be honest, I never had any acute feelings about leaving my country. In fact, I consider Chelyabinsk my second home. As long as I work or do my research, I feel comfortable here. My instructor and lab colleagues are always there for me, whether it's my work or just a walk through the city. Furthermore, SUSU launched English-language programs last year. The language will help in traveling abroad to build up my research work. I think science is the only field where people from all the countries can work together to make progress around the world. Science knows no borders.,Uvindu Wijeweera, Postgraduate Student, President of the South Ural Association of International Students and Alumni,I come from Sri Lanka, but I have been studying at SUSU for seven years: I completed my bachelor's and master's degrees in political theory and now I am a postgraduate student in my final year. My research work and future career are closely connected with history. And I am very interested in studying and analyzing the development of other countries, it is very important for a political scientist. Even as a child, I read a lot about Russian literature and, of course, in the end I wanted to see everything with my own eyes. My parents also inspired me to go to another country: my father received part of his education abroad.,In addition to a good political science education, my university invests in the recreation, sports, and social life of its students. I think this is an especially important point for humanitarian professionals on their way to harmonious and well-rounded development, and it is also of great interest to students from other countries. When I came to SUSU, they helped me adapt: they helped me to understand everyday problems and to get acquainted with the culture and classmates. Many foreigners study in English programs or study the first year in Russian at a preparatory faculty. By the way, most of the guys from other countries have never seen winter. It was in Chelyabinsk that I saw snow for the first time in my life.,The experience of working at the international student association has helped me a lot in my studies and academics. Political science is a public science, often public and communication-driven, so a leadership position has proven to be a good place to practice my communication skills.,In general, it seems to me that going through one of the stages of education abroad is a good decision for today's student. This is a great opportunity to get to know a new culture and country. Talent is appreciated in all corners of the planet, and if you have the desire to develop in big steps, the desire to work at the international level, it is worth thinking about discovering this huge world for yourself as early as possible: start from your desires and choose the best of the options.,South Ural State University English-Taught Programs,The official Telegram channel of South Ural State University。震级在地震发生的第17秒自动收敛到3.9级。对此次较大的偏差，成都高新减灾研究所表示致歉，并将尽快查明原因，改进技术、改进服务。

C | 知名主持人韩乔生也就此事发文感慨：不知道大家有没有被今早手机弹出的7.7预警吓出一身冷汗？我自己看到弹窗那一刻，也着实心里一紧。事后中国地震台网正式测定，本次地震为4.7级，震源很浅，周边多地震感明显。他指出，出现7.7级这个数字，是地震预警系统在地震发生后短短数秒内，依靠有限监测数据快速测算产生的巨大偏差，后续数值会持续迭代修正。

D | 成都高新减灾研究所也针对本次较大偏差发布情况说明并且公开致歉。

E | 韩乔生表示：亲身经历就能体会，弹窗跳出来的那一刻很容易心生恐慌。

F | 预警的初衷是为大众争取避险窗口，但初估数据客观上会存在误差。面对地震相关消息，一切还是要以中国地震台网的正式通报为准。
